Problems solved by technology

[0004] At present, the application of driving simulation technology in the optimization of traffic facilities is gradually increasing, while the attention and research on VMS are mainly focused on fonts, character heights, and layout formats. There are few related studies on the evaluation of VMS information release effects. The evaluation of the effect is mainly to carry out manual investigation on the spot, which not only wastes a lot of manpower and material resources, but also cannot guarantee the safety of the investigators during the on-site investigation.

[0076] Data example 1 in Table 3 is the data before the subjects began to visually recognize the VMS. Data example 2 in Table 4 is the data in the process of visual recognition of VMS by the subjects. Data example 3 in Table 5 is the data after the subjects visually recognize the VMS.

[0077] The running time unit is seconds. The running speed unit is km / h. Position coordinates are in meters. The data range of accelerator pedal depth and brake pedal depth is 0-1, and the larger the data, the deeper the pedal is stepped on. NORMAL means before visual recognition, FIND means visual recognition, and RECON means after visual recognition.

Abstract

The invention discloses a variable message sign information release effect evaluation method based on a driving simulation technology, and belongs to the field of road traffic management. The variablemessage sign information release effect evaluation method, based on a driving simulation technology, builds a three-dimensional scene model of a road section where the variable information board is located, obtains original data of an experimental process through driving simulation, and carries out layered calculation on three first-level and eight second-level indexes including the visual recognition effect (visual recognition time, static visual recognition distance, dynamic visual recognition distance and visual recognition angle) of a driver, the operation behavior (the brake pedal depthchange rate and the accelerator pedal depth change rate) and the vehicle running state (the visually recognized speed change rate and the speed standard deviation) according to the original data, to obtain a comprehensive evaluation result of the variable message sign road condition information release effect. According to the variable message sign information release effect evaluation method, thedata is collected through the driving simulation technology, and the evaluation result of the road condition information publishing effect of the variable information board is obtained through calculation, and the variable message sign information release effect evaluation method can be applied to selection and optimization of a newly designed variable information board and evaluation of the information publishing effect of an existing variable information sign.

Description

technical field [0001] The invention belongs to the field of highway traffic management, and relates to a method for evaluating the information release effect of a variable message sign (VMS) based on driving simulation technology. Background technique [0002] VMS is an important way to release traffic information. It can release traffic guidance information in a real-time and reasonable manner. By guiding traffic flow to reach a balanced state in the entire road network, it can alleviate traffic congestion, reduce traffic accidents, improve road network traffic efficiency, and reduce traffic pollution. At present, there are more than 400 VMS blocks in Beijing. However, due to the lack of detailed requirements for the setting of VMS in relevant norms and standards, the consideration of the external environment of actual driving is not detailed enough, and the lack of an objective evaluation system and method for the rationality and effectiveness of its setting, therefore As...
